PC -- PC's are nice because you can do what you want with them. Want to upgrade the HDD? No problem! Battery died? Let's fix it! You can do what you want with the PC. Mac users cannot customize their computer, and when the Mac needs to be serviced, it must be sent to Apple, a tedious task.

Also, the interface just seems cluttered to me.

Since Macs aren't as popular, there are less programs available for Mac, so in some cases, Mac users are SOL.
